This paper explores the claim that explanation of a group's behaviour in term of individual mental states is, in principle, superior to explanation of that behaviour in terms of group mental states. We focus on the supposition that individual-level explanation is superior because it is simpler than group-level explanation. In this paper, we consider three different simplicity metrics. We argue that on none of those metrics does individual-level explanation achieve greater simplicity than a group-level alternative. We conclude that an argument against group minds should not lay weight on concerns of explanatory simplicity.

4 Appeal to quantitative parsimony is far from uncontroversial as a means of selecting between rival explanations. Lewis, Counterfactuals, says, ‘I subscribe to the general view that qualitative parsimony is good in a philosophical or empirical hypothesis; but I recognise no presumption whatever in favour of quantitative parsimony’ (87). Alex Oliver argues that, despite our undeniable bias towards explanations with quantitative parsimony, we should not trust this as a guide to the truth (‘The Metaphysics of Properties’, Mind 105 (1996), 1–80 CrossRefGoogle Scholar).
